Enji is a short boy with big sparkly pink eyes and pink hair cut into a messy bob. His voice is bright and positive. With a cheerful and somewhat naive personality, Enji is highly impulsive, acting on every idea that he comes up with, with a tendency to drag people around him into his plans. Enji has established his own personal catchphrase, "Wonderhoy!” which he uses as a way to motivate himself and others. Though he is often in a joyful mood, Enji often neglects his more negative feelings.
